Learn the Most used technologies currently in web development

AWS is the most used Cloud computing platform by far, with over 30% market share.

PostgreSQL is the one of the most popular SQL based database engine in the world.

I dont think I need to say anything about React.

We will begin with the basics, then move onto setting up the database. We will setup the Express routes which will allow us to communicate with our database. Then we will build out the client side blog using React components. We will animate the posts and comments, then move onto something more difficult. We will begin AWS. I will give you a detailed explanation of how AWS works then we will go into a complex deployment with AWS.

Why learn SQL?

  1. SQL is the most universal and common used database language.It powers the most commonly used database engines like PostgreSQL, SQL Server, SQLite, and MySQL. Simply put,If you want to access databases then yes, you need to know SQL.

  2. It is not really difficult to learn SQL. SQL is not a programming language, it’s a query language. The primary objective where SQL was created was to give the possibility to common people get interested data from database. It is also an English like language so anyone who can use English at a basic level can write SQL query easily.

  3. SQL is one of the most sought-after skills by hiring employers.

  4. You can earn good money

How much time does it take to learn SQL?

SQL is easy but no one can determine the learning time it takes. It totally depends on you. The method we adopted to help you learn SQL quickly starts from the basics and takes you to advanced level within hours. You can follow the same, but remember you can learn nothing without practicing it. Practice is the only way to learn SQL quickly.

What are the steps I should follow to learn SQL?

  1. Start learning from the basics of SQL. The first 10 sections of the course cover the basics.

  2. Once done with the basic try your hands on advanced SQL. Next 10 sections cover Advanced topics

  3. Next few sections will cover help you with interviews and Vivas.

  4. Practice your learning on the exercise provided in every section.

What's the difference between SQL and PostgreSQL?

SQL is a language. Specifically, the "Structured Query Language"

PostgreSQL is one of several database systems, or RDMS (Relational Database Management System). PostgresSQL is one of several RDMS's, others of which are Oracle, Informix, MySQL, and MSQL.

All of these RDMSs use SQL as their language. Each of them have minor variations in the "dialect" of SQL that they use, but it's all still SQL.

Which is better, PostgreSQL or MySQL?

Both are excellent products with unique strengths, and the choice is often a matter of personal preference.

PostgreSQL offers overall features for traditional database applications, while MySQL focuses on faster performance for Web-based applications.

Open source development will bring more features to subsequent releases of both databases.

Who uses these databases?

Here are a few examples of companies that use PostgreSQL: Apple, BioPharm, Etsy, IMDB, Macworld, Debian, Fujitsu, Red Hat, Sun Microsystem, Cisco, Skype.

What's special about this course?

The course is created on the basis of three pillars of learning:

  1. Know (Study)

  2. Do (Practice)

  3. Review (Self feedback)

Know

We have created a set of concise and comprehensive videos to teach you all the SQL related skills you will need in your professional career.

Do

We also provide Exercises to complement the learning from the lecture video. These exercises are carefully designed to further clarify the concepts and help you with implementing the concepts on practical problems faced on-the-job.

Review

Check if you have learnt the concepts by executing your code and analyzing the result set. Ask questions in the discussion board if you face any difficulty.

Bonus Lectures

Apart from this, their is a bonus section which covers important topics from the view of job interviews and Vivas.

The Authors of this course have several years of corporate experience and hence have curated the course material keeping in mind the requirement of SQL in today's corporate world.

SQL Crash Course for Aspiring Data Scientist

Learn SQL and Data Science FAST with hands on labs!

"]

Students: 7727, Price: Free

The problem with online learning and self-guided learning, especially in programming, is that you are often not certain exactly where to get started on your journey. But you do know that having to run to the IT department whenever you need data pulled, or need a dataset to be created, can sometimes leave you stranded.

SQL, as an easy programming language designed for interacting with relational databases, is your starting point when it comes to anything data related. The user base of SQL is so deep that many big data technologies utilize some kind of port of SQL.

The problem with other SQL for data science classes is that, by only covering SQL itself, they leave you hanging on your journey to data science mastery, much like when you have to rely on IT to meet your data needs.

With Mass Street University, that journey does not end with bare bones knowledge of SQL. DSCI100: SQL Crash Course for Data Science is designed to quickly get you up to speed on the basics of using SQL. But this course does more than give you the SQL foundation you need to work with data.

In DSCI100, we extend your journey by teaching you some real data science. By demonstrating how Python and Apache Spark interact with SQL in hands-on labs, we teach you how SQL is actually used in a data science workflow once you have mastered the basics.

At the end of the course, you will be able to work with relational databases to pull the necessary data you need to perform complex analyses…without the assistance of IT. You will also have a good understanding of how to use SQL with common data science languages.

No other course will grant you the tools and fuel that allow you to take control of your journey. Enroll today for a real, self-sufficient path to data science excellence.

Learn to conduct vulnerability assessment with Nmap and penetration testing Metasploit framework.

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

The Metasploit Project was undertaken in 2003 by H.D. Moore for use as a Perl-based portable network tool, with assistance from core developer Matt Miller. It was fully converted to Ruby by 2007, and the license was acquired by Rapid7 in 2009, where it remains as part of the Boston-based company’s repertoire of IDS signature development and targeted remote exploit, fuzzing, anti-forensic, and evasion tools.

SQL (Structured Query Language)

SQL stands for “Structured Query Language” and can be pronounced as “SQL” or “sequel – (Structured English Query Language)”.SQL (Structured Query Language) is used to modify and access data or information from a storage area called database.

SQL Commands:

SQL commands are instructions used to communicate with the database to perform specific task that work with data.

Data Definition Language (DDL) - These SQL commands are used for creating, modifying, and dropping the structure of database objects. The commands are CREATE, ALTER, DROP, RENAME, and TRUNCATE.

Data Manipulation Language (DML) - These SQL commands are used for storing, retrieving, modifying, and deleting data. These commands are SELECT, INSERT, UPDATE, and DELETE.

Transaction Control Language (TCL) - These SQL commands are used for managing changes affecting the data. These commands are COMMIT, ROLLBACK, and SAVEPOINT.

Data Control Language (DCL) - These SQL commands are used for providing security to database objects. These commands are GRANT and REVOKE.

CREATE TABLE

CREATE TABLE table name

(column_name1 datatype,

column_name2 datatype,

column name datatype

);

table name - is the name of the table.

column_name1, column_name2.... - is the name of the columns

datatype - is the datatype for the column like char, date, number etc.
